Features, Applications

These lasers are designed as pump sources for erbium doped fibre amplifier (EDFA) applications. Processes and techniques of coupling the fibre to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilise the wavelength. Devices are available with kink free output powers to 400mW. The LC95 series pump module utilises a double Fibre Bragg Grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes.

Features Double Fibre Bragg grating stabilisation High output power, 400 mW kink free Single mode fibre pigtail Internal thermoelectric heatpump and monitor photodiode Hermetically sealed 14 pin butterfly package Telcordia GR-468-CORE in progress
